Comparison and Validation of Hydrodynamic Load Models for a Semisubmersible Floating Wind Turbine
Hegseth, John Marius; Bachynski, Erin Elizabeth; Karimirad, Madjid (Chapter, 2018)In global aero-hydro-servo-elastic analyses of floating wind turbines (FWTs), the hydrodynamic loads are usually found from potential flow theory and applied in a single point of a rigid hull. When the hull is relatively ... -
Dynamic Analysis of a Braceless Semisubmersible Offshore Wind Turbine in Operational Conditions
Karimirad, Madjid; Michailidis, Konstantinos (Peer reviewed; Journal article, 2015)The development of cost effective floating type offshore wind turbines has been desired in deep sea areas. Semisubmersible platform can be considered as a very efficient design configuration among the different type ... -
Parameter Sensitivity of Short-term Fatigue Damage of Spar-type Wind Turbine Tower
Moy, Inge (Master thesis, 2012)The World s energy demand is rapidly increasing and a good viable renewable energy source is wind power. The land-based knowledge and experience the onshore wind turbine industry possess is used to develop offshore wind ... -
Sensitivity Analysis of Limited Actuation for Real-time Hybrid Model Testing of 5MW Bottom-fixed Offshore Wind Turbine
Karimirad, Madjid; Bachynski, Erin Elizabeth (Journal article; Peer reviewed, 2017)The present paper studies the effect of limited actuation for real-time hybrid model testing (ReaTHM® testing) of a bottom-fixed offshore wind turbine in operational, parked, and fault conditions. ReaTHM® testing is a new ... -
Stochastic Dynamic Response Analysis of Spar-Type Wind Turbines with Catenary or Taut Mooring Systems
Karimirad, Madjid (Doktoravhandlinger ved NTNU, 1503-8181; 2011:8, Doctoral thesis, 2011)Floating wind turbines can be the most practical and economical way to extract the vast offshore wind energy resources at deep and intermediate water depths. The Norwegian Ministry of Petroleum and Energy is strongly ...
